My brother is on 3.1.2 jailbroken and unlocked . He has no 3.1.2 SHSH's on file because 3.13 was already out when we wanted to save the SHSHs. I'm thinking worst case scenario here: -new firmware possibly comes out (3.2?) -3.1.3 unlock comes out -we need to restore the phone for some reason (phone stuck in a loop?) -we can't restore to 3.1.2 because no shshs -we can't restore to 3.1.3 because no shshs -only option is latest un-unlockable firmware -meteor hits planet earth and the world ends as we know it So just wanted to know if/how this is possible. Can firmware umbrella do this?
